In recent years, more and more people suffering from high blood pressure. Because hypertension is a chronic, daily self-monitoring of blood pressure Digital TYPE changes in patients with hypertension has become a daily "compulsory." With the development of technology, changes in blood plastic single head stethoscope pressure occurred with each passing day, from the traditional mercury sphygmomanometer to the present electronic device, arm-type electronic device, even wrist, clip-on electronic device that Arm Semi-Automatic blood pressure monitor ... ... However, the mercury sphygmomanometer not everyone will use, the electronic blood pressure monitor is not for everyone, but many plastic stethoscope in the use of blood pressure when the operation is often not appropriate for blood pressure measurements will be affected.
